and in general, pudge much more comparable to:

- badger (embeddable db engine based on LSM Tree)

- leveldb /goleveldb (embeddable db engine based on LSM Tree)

- bolt/LMDB/pogreb (embeddable db engine with active use of MMAP)

- rocksdb and so on

redis is more about in-memory data-structures, then about key/value store.
